日照烟区烤烟最佳栽植密度研究

The Optimum Planting Density of Flue-cured Tobacco in Rizhao Tobacco Planting Area

[目的]研究日照烟区烤烟最佳栽植密度。[方法]在大田试验条件下研究了不同栽植密度对烤烟生长发育、干物质积累、经济性状的影响。[结果]随着栽植密度增加,农艺性状趋差,单株叶面积减小,公顷叶面积增加,干物质积累量降低,经济性状综合表现变好。[结论]NC55品种在栽植密度为2.1×10~4株/hm^2时较为适宜,可以获得较好的产质量。

[ Objective] To study the optimal planting density of flue-cured tobacco in Rizhao area. [ Method] Field experiment was studied under the condition of different density on tobacco growth, dry matter accumulation and economic traits. [ Result] With the increase of planting density, agronomic traits were worse, leaf area reduced, leaf area increased, dry matter accumulation decreased, while economic traits were better. [ Conclusion]2.1 × 104 plants/hm2 is more appropriate planting density for NC55 which can get a better quality of production.
